Canine Lymphoma – History, Symptoms, Treatments, & Preventions

Here's What We'll Be Covering Today

What is Canine Lymphoma?

Canine lymphoma is a type of cancer that affects a dog’s immune system. It targets lymphocytes, which are the white blood cells responsible for protecting your dog from infections. Lymphoma can show up in different parts of the body—often in the lymph nodes, spleen, or liver. While this diagnosis can be scary, many dogs with lymphoma can still live full and happy lives with the right treatment.

Why Does Canine Lymphoma Happen?

The exact reasons why lymphoma occurs in dogs aren’t fully clear, but experts think it’s a combination of genetics, the environment, and immune health. Some breeds, like Golden Retrievers and Boxers, are more likely to develop lymphoma, hinting at a genetic factor. Environmental factors, such as exposure to harmful chemicals or secondhand smoke, may also increase the risk.

When is Canine Lymphoma Typically Diagnosed?

Canine lymphoma is often found when pet owners notice symptoms like swollen lymph nodes, lethargy, or unexplained weight loss. It usually affects middle-aged or older dogs, but it can appear at any age. The sooner you spot the signs and see a vet, the better the chances of managing the disease successfully.

History of Canine Lymphoma

For many years, veterinary researchers have been working to better understand lymphoma in dogs. Discoveries in canine lymphoma have even helped inform human cancer treatments, proving once again how important our pets are not only to our lives but to the scientific community. This ongoing research means treatments for lymphoma are becoming more effective over time.

Symptoms of Canine Lymphoma

If your dog has lymphoma, the symptoms can vary depending on how far the disease has progressed. The most common sign is swollen lymph nodes, which can feel like firm bumps, often around the neck or behind the knees. Other symptoms to watch for include:

  • Loss of appetite
  • Weight loss for no clear reason
  • Low energy or unusual tiredness
  • Trouble breathing
  • Drinking or urinating more than usual
  • Digestive issues like vomiting or diarrhea

If you notice any of these signs, especially swollen lymph nodes, it’s important to contact your vet right away. Early treatment can make a big difference.

Treatments of Canine Lymphoma

While lymphoma can’t be cured, treatment can help your dog live longer and feel better. The main treatment is chemotherapy, which can give many dogs months or even years of remission. Here’s a look at some treatment options:

  • Chemotherapy: The most common treatment for canine lymphoma, it can extend your dog’s life and improve their quality of life.
  • Radiation therapy: Sometimes used to target specific areas, like swollen lymph nodes or tumors.
  • Steroids (Prednisone): These can help manage symptoms, especially if chemotherapy isn’t an option or isn’t enough on its own.
  • Immunotherapy: A newer, cutting-edge treatment that uses the dog’s own immune system to fight cancer cells.

Every dog responds differently to treatment, so your vet will work with you to find the best approach for your dog’s unique needs.

How to Help Prevent Canine Lymphoma

Although there’s no surefire way to prevent lymphoma, there are steps you can take to lower your dog’s risk:

  • Feed a healthy, balanced diet: Good nutrition helps keep your dog’s immune system strong.
  • Minimize exposure to toxins: Avoid exposing your dog to harmful chemicals like pesticides and household cleaners.
  • Routine vet check-ups: Regular visits to the vet can help catch health issues, including cancer, before they progress.
  • Know your breed’s risks: If you have a breed more prone to lymphoma, stay alert for early signs and consult your vet regularly.
